Applied analytical chemistry presents fascinating logistic problems involving the full procedure of how the sample passes through different treatment stages and finally arrives at an appropriate detector. Many of these stages are analytically trivial, for instance, filtration and dilution, while other stages may comprise complicated separation ...

Abstract The concept of a new continuous flow analyser system is described. Based on instant discrete sampling by injection into a carrier stream, the system allows continuous flow analysis to be performed in a fast, much simplified way. As the continuous flowing stream is characterized by a turbulent rather than a laminar flow, the discrete instant ...

Abstract The effect of sample volume, tube length, tube diameter, peak height and sampling rate on the determination of phosphorus in acidic plant digests was investigated, and optimal conditions for the flow injection method are described. Sampling rates of 420 samples per hour were achieved without incurring problems from carryover of samples, and ...

Radiometric detection in flow-injection analysis (Radiometric Flow-Injection Analysis)
Journal of Radioanalytical and Nuclear Chemistry Letters, 1994A single line system with a detector of radioactivity was used for the determination of60Co. In the determination, no additional chemistry is involved and limited dispersion is desirable. For this application, the FIA system is used only as a transport system for the sample up to the detector.

Flow injection analysis of pharmaceuticals
Journal of Pharmaceutical and Biomedical Analysis, 1989An overview of the most representative problems solved by flow injection analysis (FIA) in drug analysis is presented. Different aspects of this technique which can be manipulated with specific purposes are discussed and special emphasis is placed on the possibilities of FIA in dissolution test control.

Flow-reversal flow-injection analysis Enhancement of flow-injection titrations
Talanta, 1991Most FIA applications involve simple unidirectional continuous-flow regimes. This paper continues the development of the flow-reversal (frFIA) approach and its applications. Flow-reversal flow programming achieves flexibility in operation without requiring manifolds to be refitted. The sensitivity of FIA titrations can be increased by use of frFIA.

Reverse flow-injection analysis
TrAC Trends in Analytical Chemistry, 2012Abstract Reverse flow-injection analysis (rFIA) involves injection of the detection reagent into a mobile phase of sample. rFIA is one of the FIA modes used to minimize reagent consumption, decrease sample dispersion, improve mixing efficiency and enhance the sensitivity.
